How to configure to use MII on PRU_ICSSG?

There is no signal name in the SIGNAL NAME column in the "Table 6-1. Pin Attributes (ALV, ALX Packages)" on the datasheet that indicates MII on PRU_ICSSG.

The Mux Mode is 0 or 1 for MII on PRU_ICSSG in the SysConfig tool. It indicates the GPO or GPI on PRU_ICSSG in the SIGNAL NAME column in the "Table 6-1. Pin Attributes (ALV, ALX Packages)" on the datasheet.

The MII appears to be multiplexed with RGMII in "Figure 6-151. PRU_ICSSG0 External Interface I/Os" or "Figure 6-152. PRU_ICSSG1 External Interface I/Os" on the TRM.

Is the Mux Mode configuration in the SysConfig tool correct?

Hi Frank-san,

Thank you for your reply.

Our customer is confused because there is no signal name that indicates MII signals on PRU_ICSSG in the SIGNAL NAME column in the "Table 6-1. Pin Attributes (ALV, ALX Packages)" on the datasheet.

Is GPO or GPI in the SIGNAL NAME column (0 or 1 in the MUX MODE column) used for each of the MII signals on PRU_ICSSG?

0 or 1 in the MUX MODE appears to be used for each of the MII signals on PRU_ICSSG in the SysConfig tool.

Best regards,

Daisuke

0 or 1 in the MUX MODE appears to be used for each of the MII signals on PRU_ICSSG in the SysConfig tool.

Please check that the MUX MODE is 0 or 1 for each of the MII signals on PRU_ICSSG in the files generated by the SysConfig tool.

Best regards,

Daisuke

Hi Nilabh A-san,

I understand that each of the MII signals is internal multiplexed for the PRU_ICSSG.
